Am I missing something here guys (and gals)?  When the FIFO is
enabled the THRE bit in the Line Status Register is set whenever
the FIFO can accept additional characters.  So if it were clear,
isn't that an indication the FIFO is full?
As for RS-485 transceiver turn-around; the TEMT bit also in the
Line Status Register, can be used to determine when the stop bit
of the last character has been transmitted.  Can't that be used
to control the RS-485 interface?
